IgG4:IgG ratio of pulmonary nodular lymphoid hyperplasia. The IgG4:IgG ratio varied in this study. The ratio in case 1 was less than 0.1 (A, IgG; B, IgG4). The ratios in case 5 (C, IgG; D, IgG4) and case 6 (E, IgG; F, IgG4) were approximately 0.1–0.2, which is not compatible with IgG4-related disease.
